Focus on Traumatic Brain Injury Research

NINDS TBI Classification and Nomenclature Workshop
Bethesda, MD

January 22-23, 2024

Post Event Summary information is now available.

Traumatic brain injury (TBI) occurs when external physical forces cause damage to the brain, whether from impact, penetrating objects, blast waves or rapid movement of the brain within the skull.  TBI severity has been classified as mild, moderate or severe based primarily on the Glasgow Coma Scale in combination with an assessment of periods of loss/alterations of consciousness and imaging scans of the brain.  The classification of mild TBI also includes concussion, commonly defined as a transient alteration of brain function after exposure to external physical forces. While short-term TBI can be life threatening in some cases, TBI also can have long-term sequelae including cognitive dysfunction, pain, sleep disorders and physical disability collectively known as the post-concussion syndrome (PCS). PCS results when various symptoms of TBI last weeks, months or more than a year following the TBI incident.  Chronic traumatic encephalopathy (CTE) is a delayed neurodegenerative disorder that was initially identified in postmortem brains and, research-to-date suggests, is caused in part by repeated traumatic brain injuries. NINDS supports ongoing efforts to refine diagnostic criteria for both CTE (postmortem diagnosis) and the associated Traumatic Encephalopathy Syndrome (TES; diagnosis in the living).

The TBI program at NINDS provides support and funds to extramural researchers studying basic, clinical and translational TBI research. NINDS-funded research includes studies to understand mechanisms of TBI and its sequelae, preclinical and clinical studies for diagnosis, prognosis, potential therapeutics, and other aspects of TBI.

Additional general information about TBI can be found at the NINDS TBI Disorder information page.
